The invention provides a triangular truss installing and lifting device which comprises a lifting machine, a supporting column and a triangular truss, a lifting box is arranged at one end of the lifting machine, a rotating shaft is arranged in the lifting box in a running fit mode, a pull rope is wound on the peripheral side of the rotating shaft, a telescopic rod is arranged on the lower side of the lifting box, a lifting rod is arranged at the bottom of the telescopic rod, and one end of the lifting rod is fixed to the pull rope; the other end of the lifting rod is rotationally matched with a rotating block corresponding to the triangular truss, and a limiting plate corresponding to the telescopic rod is arranged in the lifting box. According to the lifting device, the telescopic rod is installed on the lower side of the lifting box, the pull rope is placed in the telescopic rod, and compared with the pull rope, the telescopic rod is not prone to shaking or the shaking amplitude is small, so that the situation that the triangular truss shakes can be reduced, meanwhile, the rotating block is installed at one end of the lifting rod, the inserting rod is installed on the lower side of the limiting plate, and the blocking rod is installed on the lower side of the lifting box; in this way, the triangular truss can be limited through the inserting rods and the blocking rods.

    本发明提供一种三角桁架安装起吊装置,包括起吊机、支柱和三角桁架,所述起吊机的一端装设有起吊箱,起吊箱内转动配合有转轴,转轴的周侧缠绕有拉绳,起吊箱下侧装设有伸缩杆,伸缩杆的底部装设有吊杆,且吊杆的一端与拉绳固定,吊杆的另一端转动配合有与三角桁架相对应的转动块,起吊箱内装设有与伸缩杆相对应的限位板。在本发明中,在起吊箱下侧安装伸缩杆,将拉绳放在伸缩杆内,相较于拉绳,伸缩杆不容易晃动或者晃动幅度较小,因此可以减少三角桁架发生晃动的情况,同时在吊杆的一端安装转动块,在限位板的下侧安装插杆,在起吊箱下侧安装档杆,这样就可以通过插杆和档杆对三角桁架进行限位。
